WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 633,768, dated September 26, 1899.

Application filed $eptemher 19, 1898. Serial No. 691,839. (No model.)

To all whom, it may concern.-

Be it known that I, MICHEL SOHAACK, a citizen of Luxemburg, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a water-heater, the object being to provide a simple, cheap, and efficient device of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a top plan view of a water-heater constructed in accordance with my invention. Fig. 2 is a central vertical section of the same on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4: is a similar section on the line 4 4 of Fig. 2. Fig. 5 is a fragmentary edge elevation of one of the plates. Fig. 6 is a detail sectional view on the line 6 6 of Fig. 1.

Referring now to said drawings, A indicates a cylindrical casing consisting of a plurality of interfitting sections a, mounted one upon the other. Each of said sections a, except the lowest, is provided with a comically downwardly inclined bottom plate 1, provided with a central opening 2, below and around which an inversed cone 3 of wire-cloth is secured. A solid plate a of similar shape to the plate 1, but inversely inclined, is mounted below each of said plates 1, being held by the springs 5, secured to the walls of said sections, and bent at their lower ends to form corrugations 6, in which the edges of said plates aare held. Said plates 4 are of smaller diameter than said sections a, so as to leave annular passages 7 between said plates and the wall of said casing. Each of said bottom plates 1 and said solid plates 4 is provided with corrugations 8, extending practically tangentially from said openings 2 in said plates 1 to the outer edges of said plates and, in the case of the plates 4, from a corresponding central plane portion 9 to the outer edges of the sheets.

Mounted upon the plate 1 of the uppermost section a is a ring 10', concentric with and adjacent the outer wall, so as to form an annu lar passage 11 between said ring 10 and said wall of said section. A feed-pipe 12 enters said annular space 11 and feeds the Water thereto. Below the delivery end of said pipe is an iuversed-V-shaped plate 13,which serves tocause the water to fiow equally around said annular passage in opposite directions, thus serving to distribute it more equally over the plate 1. The water flows from said annular passage 11 through interstices formed by the depressed corrugations of said plate and follows said corrugations to the center, whence it flows upon the wire-screen cones 3, which serve to guide it to the center of the plate anext below said upper plate 1. Thence it flows toward and over the outer edges of the plate 4 upon the next plate 1, and so on until it flows over the edge of the lowest plate a, and thence into an annular passage 14 formed adjacent the outer wall of the lowest section a, by the annular plate 15, which is V-shaped in cross-section and inverted, thus leaving a central opening 16 in the bottom of the lowermost section. An outlet-pipe 17 leads from said annular passage 14.

The casing A is supported upon legs 18 over a gas-stove or other heater, the heat from which passes upwardly in a direction always opposite to the flow of water. By bringing the hot gases in direct contact with the water I find that all the heat is absorbed thereby and the water heated to a very appreciable extent during its passage from the inlet to the outlet end of the device.

The advantage obtained by the wirecloth cones 3 is that the water is guided by same and instead of dripping directly down from the edges of the openings follows the surface of the cone and drips from the apex of the latter, and at the same time it is retained in a finely-divided state, and is thus brought more directly into contact with the hot gases, while at the same time greater resistance is ofiered. to the passage of the latter, thereby preventing the waste of the heat.

I claim as my invention- 1. A Water-heater comprising a plurality of cylindrical sections adapted to be mounted upon each other, the uppermost section havin g a bottom downwardly inclined toward its center, a central opening in said bottom, an inverted perforated cone depending from said bottom around said opening, and a water-supply leading to said section, the lowermost section having a bottom open at its central portion and provided with an annular receptacle, a plate of less diameter than said section centrally mounted above said receptacle and inclined downwardly from its center to its edge, and a water-outlet from said receptacle, and the intermediate sections being each provided with a bottom coinciding in structural featu res with said bottom of said uppermost section, and each provided with a plate mounted above said bottom, and coinciding in structural features with said plate in said lowermost section, substantially as described.

2. In a water-heater, a plate inclined downwardly from its edges to its middle portion, a central opening in said plate, and an inverted perforated cone secured to said plate around said opening and adapted to receive water therefrom and deliver same from its apex, said perforations in said cone being adapted to permit the passage of heated gases therethrough, substantially as described.

3. In a water-heater, the combination with a plurality of plates mounted in a casing, each inclined downwardly from its outer edges to its middle portion, and provided with a central opening and an inverted perforated cone secured around said opening, of plates of less diameter than said casing centrally and removably mounted therein between said firstnamed plates and inclined downwardly from their middle portions to their edges, whereby water poured upon the uppermost plate will pass downwardly'in a zigzag course and be finely divided, and means for supplying heated gases to said heater adapted to pass upwardly therethrough, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
